Agnirva Space Premier League - Expedition #31550: DUPLEX CubeSat: A Dual-Powered Leap in Satellite Propulsion

Satellites have revolutionized how we explore space, but they face a major challenge: propulsion. The Dual Propulsion Experiment, or DUPLEX, CubeSat addresses this by testing two propulsion systems in one small satellite. Led by CU Aerospace LLC and NearSpace Launch, DUPLEX was launched to the ISS during Expedition 74.

CubeSats are small, modular satellites that are inexpensive and fast to build. However, their size limits onboard propulsion, making it difficult to maneuver once deployed. DUPLEX solves this by combining two systems: an electric propulsion unit and a chemical propulsion unit. Together, they offer flexible options for satellite movement and orientation.

Electric propulsion uses ionized gas and electricity to produce thrust. It's efficient and ideal for long-duration missions. Chemical propulsion, on the other hand, provides short bursts of powerful thrust, useful for quick adjustments. By integrating both, DUPLEX can adapt to different mission needs—such as evading debris or changing orbits.

The experiment's success could transform satellite capabilities, especially for small spacecraft in low Earth orbit. It opens doors to more agile and responsive missions, crucial for Earth observation, communication, and even planetary exploration.

DUPLEX demonstrates how compact spacecraft can evolve with smart engineering, offering future space missions greater freedom and safety.
